- Mechanism of Action
- Stimulates endogenous GH release from anterior pituitary via GHRH and ghrelin receptor agonism
- Direct delivery of synthetic GH into systemic circulation
- Peptides preserve pituitary function; HGH bypasses it entirely
- GH Secretion Pattern
- Pulsatile (6–10 peaks/day, maintained circadian rhythm)
- Non-pulsatile sustained elevation (flattens natural rhythm)
- Peptides replicate physiological pattern; HGH does not
- IGF-1 Elevation
- 55–72% increase from baseline (ceiling ~300–400 ng/mL)
- Linear dose-response (can exceed 500 ng/mL at high doses)
- HGH allows higher IGF-1 targets; peptides plateau
- Endogenous GH Suppression
- None. Endogenous secretion remains intact
- Negative feedback suppresses pituitary for 4–8 weeks post-cessation
- Peptides allow immediate recovery; HGH requires washout
- Dosing Frequency
- 2–3× per week (CJC-1295 half-life 6–8 days)
- Daily subcutaneous injection (half-life 2.5–3 hours)
- Peptides require less frequent administration
- Regulatory Classification
- Research-grade peptides (not FDA-approved drugs)
- FDA-approved prescription drug (tightly controlled)
- HGH carries stricter regulatory burden
